It's the first new "positive" ad the president has gone up with in more than a month. (Positive in quotes because the president takes a shot at Romney's economic plan, but this is not a traditional attack ad like the campaign has been running.)

The campaign did not release the size of the buy, but says it will be running in Colorado, Florida, Iowa, North Carolina, New Hampshire, Nevada, Ohio, Pennsylvania, and Virginia

Here's the script:

"Over the next four months you have a choice to make. Not just between two political parties or even two people. It's a choice between two very different plans for our country. Governor Romney's plan would cut taxes for the folks at the very top, roll back regulations on big banks, and he says that if we do our economy will grow and everyone will benefit. But you know what? We tried that top-down approach. It's what caused the mess in the first place. I believe the only way to create an economy built to last is to strengthen the middle class. Asking the wealthy to pay a little more so we can pay down our debt in a balanced way. So that we can afford to invest in education, manufacturing, and homegrown American energy for good middle class jobs. Sometimes politics can seem very small. But the choice you face, it couldn't be bigger."
